Retailers are now the dominant partners in most supply systems and have used their positions to re-engineer operations and partnerships with suppliers and other logistic service providers. No longer are retailers the passive recipients of manufacturer allocations, but instead are the active channel controllers organizing supply in anticipation of, and reaction to consumer demand.

If considers this transformation through an examination of the fashion, grocery and selected other retail supply chains, drawing on practical illustrations. Current and future challenges are then discussed.
